High-efficiency sulfenamide accelerator based on tetramethylthiuram monosulfide (TMTM) for fast and controllable vulcanization.
Masterbatch formulation with 80% active ingredient content in a non-dusting, free-flowing EPDM carrier matrix.
Excellent scorch safety combined with rapid cure onset—ideal for high-speed tire and industrial rubber processing.
Good dispersibility in both natural rubber (NR) and synthetic elastomers including SBR, BR, and NBR.
Low volatility and enhanced storage stability compared to conventional TMTM powders.
Tire treads and carcasses requiring balanced processing safety and crosslink density.
Industrial rubber goods such as conveyor belts, hoses, and rollers.
Automotive vibration-damping components and engine mounts.
Technical molded parts demanding reproducible cure profiles and low compression set.
